Five hundred years ago, the fallen angel Lucifer drifted into a different world, rebelled against an oppressive empire, and overthrew it. However, this act went against the will of the world's creator, the false god Yaldabaoth. The false god unleashed his minions, the Seraphim monsters, causing a great catastrophe known to later generations as the "Seraphim Disaster." Lucifer bound the false god deep within another dimension, sealed the entrance, and departed for a different world after averting the crisis. The place where the entrance was sealed became known as the "Tower," serving as a legendary symbol of the savior Lucifer. Five hundred years after the Seraphim Disaster, the seal on the Tower began to fray due to Yaldabaoth, who had been tenaciously gathering strength by calling upon the darkness in people's hearts from across the dimensions. Around that time, El, a high school girl who had lived sixteen years as an ordinary girl, began to hear a strange "sound" that only she could perceive. It was then that she was discovered by Amon, a demon claiming to be a "loyal servant of Lord Lucifer." El learned that she was the "vessel" inheriting the power of the fallen king Lucifer and was born to fight the false god. Her ordinary daily life, where she had been worrying about her future career in modern society, suddenly changed. El was thrust into a surreal role she couldn't quite grasp. However, at that moment, the Seraphim—vanguards sent by Yaldabaoth through the fraying seal—materialized and began attacking the city. The "sound" El had been sensing was actually a sign of the Seraphim's appearance. Forcibly given a weapon by Amon, El stood up to the Seraphim to save her friends in the city despite her confusion. Contrary to her own hesitation, El naturally mastered the hidden power inherited from Lucifer, repelling the Seraphim while flying on wings of light. Personality At first glance, she seems cool and lethargic, but she is a sincere and hard worker.
